The big news from Weistec on the McLaren SLR front last month was that they are in the process of developing a twin turbo upgrade package for the SLR. However, Weistec has more products available for the Mercedes McLaren SLR than just turbos. Weistec has a power upgrade package for the Kompressor/Supercharger OEM M155 V8 motor which boosts output to 715 horsepower and and 705 lb-ft of torque at the crank.

What you see in the videos below is the upcoming Mercedes answer to the BMW X6. Yes, the four-door 'coupe' style SUV market is heating up. Basically, the MLC will just be an M-Class but with different styling. Essentially how BMW makes the X6 based on the X5 architecture. This means the transmission and engine choices will all carry over. It also means we will see an MLC63 AMG as spyphotos from earlier this year showed.

Mercedes is still way out in front of everyone but the Hungarian Grand Prix ended up with Red Bull Racing taking the victory and it was not Sebastian Vettel as we have become accustomed to. Daniel Ricciardo took the checkered flag with excellent driving. He was followed by Ferrari's Fernando Alonso and Lewis Hamilton of Mercedes who provided a great race and excellent finish. Nico Rosberg finished behind teammate Hamilton for fourth place.

Big news here from Weistec Engineering who has managed to keep their Mercedes-Benz McLaren SLR twin turbocharger development under wraps until now. The Mercedes-Benz McLaren SLR as you know has an M155K supercharged 5.5 liter AMG V8 which is based on the M113K supercharged 5.5 liter V8 familiar to us from the W211 generation E55 AMG. Weistec decided to remove the supercharger on the SLR and add a pair of turbochargers in.

Very nice tuning results here courtesy of BrenTuning. The car in question is a 2007 W211 generation E63 AMG. This car has the naturally aspirated 6.2 liter M156 V8. The baseline with the charcoal air filters removed and airbox modifications is 415 horsepower to the wheels and 416 lb-ft of torque at the wheels.

The G63 6x6 AMG is an absolutely insane monster of a vehicle that is basically a twin turbo all wheel drive German tank with power sent to six wheels. Brabus is importing these G63's as MBUSA does not at $850k+ a pop. What you may not know is that Weistec is also importing these 6x6 G63 AMG's. Not only are they importing them but they are also upgrading them with the bevy of tuning parts available in the Weistec M157 AMG engine catalog.

Diesel sales are on the rise. Audi USA diesel sales are on a dramatic rise with sales increasing four times in 2014 over 2013. That is a huge jump and it should show to German executives that Americans not only like the idea of diesels, they buy them. For some reason the Germans continue to think Americans do not want diesels and they reserve their best diesel models for Europe. This is not just Volkswagen but Audi and BMW as well.

It is nice to see before and after dragstrip comparisons like this. Before and after dyno results for various forced induction kits are plentiful but actual real world before and after 1/4 mile runs are far more rare. What we have here is a stock W204 C63 AMG coupe running at the PBIR (Palm Beach International Raceway) dragstrip in Florida. The baseline 1/4 mile run is a 12.502 second pass at 112.38 miles per hour.

Weistec has officially begun their M133 AMG 2.0 liter direct injected four-cylinder tuning era. The new AMG motor is getting a lot of attention from tuners but so far the majority of the tuning has been based around piggyback tuning boxes. Weistec is taking a different approach and supplying the market where it was lacking with quality hardware. This includes exhaust pieces such as a downpipe and midpipe as well as a turbocharger heat shield.

You did not think AMG was just going to stick their monster 6.0 liter M279 twin turbo V12 in the W222 S65 AMG sedan did you? The S-Class coupe also gets the twin turbo V12 treatment and the result is a 621 horsepower and 738 lb-ft of torque monster of a car. The engine is mated to a AMG SPEEDSHIFT PLUS 7G-TRONIC transmission that is upgraded to be able to handle enough torque to seemingly alter the rotation of the earth.

The pictures you see are of the two door W205 based C-Class convertible. The car is expected to make its debut sometime later this year (likely at the Los Angeles International Auto Show) and will share the powertrain options of the W205 C-Class sedan. The photos show a hard top but it is there to camouflage a folding soft top. The soft top likely was chosen to keep weight down on the convertible model so no folding hardtop like the SLK or SL.
